Membrane separation technology is of great research interest in industry owing to its unparalleled merits such as high selectivity with unsuppressed permeability, reduced carbon footprint, small capital investment, and low energy consumption in comparison to traditional separation techniques. In the last few decades, polyamide membranes dominate the membrane industry until the porous organic polymers (POPs) get a ticket into the area of membrane separation. POPs bearing rich pore architectures and feasible functionalization are ready for fabricating novel membranes for rapid and precise molecular sieving. Here, a background overview of separation technology is provided, followed by a brief introduction of various POP-based membranes and the fabrication approaches of these membranes. Then, recent advancements of POP-bases membranes in energy-saving applications including gas separation and liquid separation are highlighted together with discussions about membrane design and generation involved. Finally, a concise conclusion with our perspective and challenges remaining for the future development of POP-based membranes are outlined.

与传统分离技术相比，膜分离技术具有无可比拟的优点，如选择性高、渗透性不受抑制、碳足迹减少、资本投资小、能耗低等优点，在工业界引起了极大的研究兴趣。在过去的几十年里，聚酰胺膜在膜工业中占据主导地位，直到多孔有机聚合物 (POP) 进入膜分离领域。具有丰富的孔结构和可行的功能化的 POP 已准备好制造用于快速和精确分子筛分的新型膜。在这里，提供了分离技术的背景概述，然后简要介绍了各种基于 POP 的膜以及这些膜的制造方法。然后，以 POP 为基础的膜在包括气体分离和液体分离在内的节能应用中的最新进展被重点介绍，同时讨论了所涉及的膜设计和生成。最后，简要总结了我们的观点和未来发展 POP 膜所面临的挑战。
